Eye diagram opening factor measurment


#1

Hi,

The eye opening factor is defined in Interconnect as (EO=(μ1-μ0-(σ1-σ0))/EA) ; with EA=μ1-μ0. Shouldn’t it be (EO=(μ1-μ0-(σ1+σ0))/EA) ?

Thanks,

Maxime

Hi Maxime,

You are correct about the equation!!! We dug up in the codes and the good news is that, the calculation in the Eye Diagram element is correct using the equation EO=(μ1-μ0-(σ1+σ0))/EA, and the same thing for the eye height definition. So you can still trust the results, tt is only the documentation is wrong and we will correct it shortly. Thank you for raising this up :slight_smile:
